思科7604 + RSP720 3 3CXL +WS-X6704-10 WS标识问题

Question

思科7604 + RSP720 3 3CXL + WS-X6704-10GE，需要了解来自客户端的流量有多少流入外部资源，以及有多少流向内部网络资源。

将传入通信量标记为外部资源：

    interface TenGigabitEthernet3/4.AAA
 description -= WORLD =-
 encapsulation dot1Q AAA
 ip address XXX.XXX.XXX.XXX XXX.XXX.XXX.XXX
 service-policy input WORLD-IN-MARKING
 service-policy output WORLD-OUT-SHAPING
end

#sh policy-map WORLD-IN-MARKING
  Policy Map WORLD-IN-MARKING
    Class class-default
      set dscp cs1

检查是否通过策略映射：

#sh policy-map interface Te3/4.AAA input
 TenGigabitEthernet3/4.AAA

  Service-policy input: WORLD-IN-MARKING

    class-map: class-default (match-any)
      Match: any
      set dscp 8:
      Earl in slot 1 :
        164559208445 bytes
        5 minute offered rate 788760744 bps
        aggregate-forwarded 164559208445 bytes

与图形加载接口相同的bps。

客户端接口：

interface TenGigabitEthernet3/4.BBB
 description -= CLIENT =-
 encapsulation dot1Q BBB
 ip address YYY.YYY.YYY.YYY YYY.YYY.YYY.YYY 
 service-policy output CLIENT-W-IN
end

#sh policy-map CLIENT-W-IN
  Policy Map CLIENT-W-IN
    Class WORLD-IN
     police cir 1000000000 bc 31250000
       conform-action transmit
       exceed-action drop

检查是否通过策略映射：

#sh policy-map interface TenGigabitEthernet3/4.BBB
 TenGigabitEthernet3/4.BBB

  Service-policy output: CLIENT-W-IN

    class-map: WORLD-IN (match-all)
      Match:  dscp cs1 (8)
      police :
        1000000000 bps 31250000 limit 31250000 extended limit
      Earl in slot 1 :
        411124 bytes
        5 minute offered rate 2568 bps
        aggregate-forwarded 411124 bytes action: transmit
        exceeded 0 bytes action: drop
        aggregate-forward 2216 bps exceed 0 bps

    Class-map: class-default (match-any)
      0 packets, 0 bytes
      5 minute offered rate 0000 bps, drop rate 0000 bps
      Match: any

bps显示的值比图形加载接口中的值小得多。

类似的方案在思科ASR1001上也能很好地工作。

尝试标记dscp af11，然后设置dscp cs1 -无更改。

我怎么才能解决这个问题？

Answer 1

以上描述的行为是针对Cisco76XX平台设计的:参见思科7600's QOS配置指南。

解决了在发送到该路由器之前在另一个路由器上标记流量的问题。
